简单实现分行输出的javascript代码

  在c#里只要在字符串前加上@符号，变可以让字符串随意换行，如下代码所示：

string stroutput=string.Format(@"<table width='100%' border='0' align='center' cellpadding='3' cellspacing='0' style='margin-top:10px;'>
                    <tr>
                        <td>　你好！<b>{0}</b>  [ <a href='{5}' >个人信息</a> ， <a href='http://forum.mkd.com/logout.aspx?userkey={1}'>退出</a> ]</td>
                    </tr>
                    <tr>
                        <td>　积分：<b>{2}</b>  </td>
                    </tr>
                    <tr>
                        <td>　等级：<b>{3}</b></td>
                    </tr>
                    <tr>
                        <td><hr style='height:1px;border-top:0px; border-style:dashed; border-left:0px; border-right:0px; border-color:black;' /></td>
                    </tr>
                    <tr>
                        <td>　新短消息 <a href='http://forum.mkd.com/usercpinbox.aspx' target='_blank'><font style='font-weight:bold; color:#B90000;'>{4}</font></a> ， <a href='http://forum.mkd.com/usercpsubscribe.aspx' target='_blank'>收藏夹</a> ， <a href='http://forum.mkd.com/usercpprofile.aspx' target='_blank'>管理</a></td>
                    </tr>
                    </table>", string.IsNullOrEmpty(userInfo.Nickname) ? userInfo.Username : userInfo.Nickname, userInfo.Password.Substring(4, 8).Trim(), userInfo.Credits, UserGroups.GetUserGroupInfo(userInfo.Groupid).Grouptitle, userInfo.Newpmcount, Urls.UserInfoAspxRewrite(userInfo.Uid));

  而javascript里是不支持字符串的换行的，所以要将stroutput这个字符串输出通常需要一行一行来，在这我用了string.Split的方法来实现避免一行一行的手工输出：

        private void write(HttpContext context, string line)
        {
            line = line.Remove(line.Length - 1, 1);
            context.Response.Write(string.Format("document.write(\"{0}\");\r\n",line));
        }

                   string stroutput=string.Format(@"<table width='100%' border='0' align='center' cellpadding='3' cellspacing='0' style='margin-top:10px;'>
                    <tr>
                        <td>　你好！<b>{0}</b>  [ <a href='{5}' >个人信息</a> ， <a href='http://forum.mkd.com/logout.aspx?userkey={1}'>退出</a> ]</td>
                    </tr>
                    <tr>
                        <td>　积分：<b>{2}</b>  </td>
                    </tr>
                    <tr>
                        <td>　等级：<b>{3}</b></td>
                    </tr>
                    <tr>
                        <td><hr style='height:1px;border-top:0px; border-style:dashed; border-left:0px; border-right:0px; border-color:black;' /></td>
                    </tr>
                    <tr>
                        <td>　新短消息 <a href='http://forum.mkd.com/usercpinbox.aspx' target='_blank'><font style='font-weight:bold; color:#B90000;'>{4}</font></a> ， <a href='http://forum.mkd.com/usercpsubscribe.aspx' target='_blank'>收藏夹</a> ， <a href='http://forum.mkd.com/usercpprofile.aspx' target='_blank'>管理</a></td>
                    </tr>
                    </table>", string.IsNullOrEmpty(userInfo.Nickname) ? userInfo.Username : userInfo.Nickname, userInfo.Password.Substring(4, 8).Trim(), userInfo.Credits, UserGroups.GetUserGroupInfo(userInfo.Groupid).Grouptitle, userInfo.Newpmcount, Urls.UserInfoAspxRewrite(userInfo.Uid));
                    string[] aroutput =stroutput.Split('\n');
                    foreach (string temp in aroutput)
                    {
                        write(context, temp);
                    }

 原理就是利用回车换行符来分割字符串，达到分行输出的目的。
